The Mineral Plus+ Calcite Cartridge System adds back in the essential minerals (calcium & magnesium) to your drinking and cooking water which are removed from RO systems and Ultra filtration systems.

What does the Calcite Post Cartridge do? back to top
When installed after an RO system, this cartridge adds beneficial and needed calcium and magnesium back into the water. RO systems remove nearly 99% of all minerals and anything else from the water. Adding this after your RO will help keep your water balanced and full of beneficial minerals.

As advertised

System continues to work well, and as advertised. We change our sediment filter every 6 to 9 months, and changed the charcoal at about 3 years. Our system treats all domestic water, and our landscape irrigation emitters. Significant reduction in scale at faucets at landscape emitters. The other day we had guests at our home, and I parked my car in front of a neighbors house. I was shocked to see the mineral deposits on my car from a bit of irrigation over-spray from their untreated water during the night. No such deposits around our house, at our shower heads, in our coffee pot, or even in our recirculating water-wall fountain. Thank you, Pelican.

Solid sales/customer service

I spoke with Phil on the phone and received helpful information regarding the NS3 and local installers in my area while researching what unit to purchase. I later purchased the NS3 with Phil's assistance and had additional questions quickly answered. Easy, simple process.

What a Blessing! On a Saturday afternoon while my plumber is replacing the 2nd heating element at our rental house in 6 months due to heavy sediment {just replaced hot water tank last year & 2 other times in the last 9yrs)--I got online & stumbled on Pelican's website. I called and got "Phil". Thank God!! I explained my situation & he directed me to what system I needed, he is so knowledgeable!! The best part was he recommended the less expensive system, based on our well GPM-instead of upselling me!! Integrity & honesty is so rare these days, & he showed true concern & helpfulness. His knowledge of plumbing, wells & water tables is amazing! He also advised us how to install it over online chat (fittings and all! I am a customer for life. He is saving me so much money in the long run! Thank you Phil, you're a wonderful person-you made my weekend! Lisa Frye

All of the reps gave us the information we needed and listened to us, a rare quality these days. Good team.

I told you I am not a computer user. You all were great and I am glad to have done business, even on a Saturday. Thanks for your help. Monica

So far, so good

I ordered my NS3 water softening system yesterday, and spoke with Phil. He was extremely helpful and answered all my questions. He gave me his phone extension should I have any problems. He made me feel very confident that I had made a good choice. I expect to receive the equipment next week and am looking forward to enjoying my new water softener. Hopefully there won't be any problems with delivery, installation or performance.

No maintenance

At my age hauling bags of salt is no longer practical. It also saves water since there is no longer any need to back flush the system. For older folks it's great to have a hassle free system!! Bill

Love it!

The water filter system is awesome. The only maintenance required is 1 time every 5 years! Customer service is exceptional. I spoke with Phil who offered to walk me through the replacement of the carbon filter. Doesn't get better than that!
